Microstructure and Texture Optimization in Fe-Si Ferritic Steels
The ferromagnetic properties of ferritic steels are known to strongly depend on the direction of magnetization. The <100> are the axes of spontaneous magnetic moments and hence the directions of easy magnetization. Materials displaying a <100>//ND texture are ideal not only for transformer but also for rotating machines due to their isotropic magnetic character. In the present study the potential of severe plastic rolling deformation is investigated. The cold rolling and annealing microstructures and textures are identified with increasing rolling strains to a maximum vM equivalent of 8.0. It is shown that excessive rolling reduction is capable of producing non-conventional texture components with promising potential for magnetic applications.
